I highly disagree with that website. I'm no Andy Cutler die hard follower but the hundreds of autistic and mercury toxic patients at my environmental MD's office that were treated for heavy metal using PROPER (I emphasize proper because most docs and naturopaths don't know how to chelate properly) have gotten significantly better. Dr. Buttar has treated thousands of patients and still holds public to any doctor who challenges his philosophies and medical and clinical findings, the challenge to consume equal amounts of mercury as a testament to his treatment. My own doctor has cured his son (and Dr. Buttar of his own son) of autism. Anecdotal evidence is one thing but there are tons of medical literatures on this subject. Chelation CAN be the "bull" that runs into the room and destroys everything if not done properly. Think DMPS injection or push IV.
